This lightweight daypack, with a capacity of 19 liters, is perfect for day hikes. The main material, TX70 Ultra, is a high-performance fabric from CHALLENGE SAILCLOTH's ULTRA series, utilizing UHMWPE (Ultra High Molecular Weight Polyethylene), boasting a strength about 15 times that of steel by weight. Despite its thin and lightweight design, it is resistant to tearing and abrasion, offering excellent durability. The shoulder harness features a pattern designed for moderate cushioning and comfortable wear. It includes mesh pockets on both sides for holding bottles or trekking poles and a bungee cord on the front for attaching a shell, sandals, or a lightweight tent mat. Additionally, the back foam is removable, and the waist belt can be stowed depending on the use case.

Reviews
Husband Purchase
I fell in love at first sight and bought it.
It's light and durable.
I bought it to go on a trip and used it right away.
I was saying it would be nice to have another pocket on the outside.
